We are a module manufacturer. We have designed a module based on WL33. We have been using ST's dk board for verification. However, when we tested the distance, the original dk board was about 200 meters. With a 20dbm and -12X sensitivity, we have high expectations for this chip. Do you have ST distance test reports and parameters? 2. If our deviation is <2.5Khz, does it mean that we need to replace the TCXO?
I propose to evaluate the performances of two RF settings:
First RF configuration:
Data rate=200 kbps
Frequency deviation = 100 kHz
Channel filter= 400 KHz
DSSS = 16
Second RF configuration:
Data rate=100 kbps
Frequency deviation = 50 kHz
Channel filter= 200 KHz
DSSS = 16
